UNITED ,STATES PATENT- ori-"ICE,"

nnnuoim .1. roam, or vALLEJo, camcom Be it known that I, REDMOND J.TOBIN, a A citizen of the United States, residin at Vallejo, in thecounty of Solano and tate of California, have invented new and usefulImprovements in Torches, of whichthe following is a specification.

This invention has reference to a novel construction of weldin or cuttintorch, and particularly to toro es of the c ass em ploying a mixture ofoxygen and acetylene to produce the welding or cutting flame.

The principal ob'ectof `the invention is to produce a torch, t e nozzleof which may be moved into different positions without twisting orrotating the handle or hose con- 'nected therewith.

Among other features the invention includes means for hingedly securingthe nozzle to the head and for rotatably securing said head to the hosecarrying stem so that the two joints provide a substantially uni-Yversal connection between the parts.

The invention also consists in certain other features of constructionand in. the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will' be had to theaccompanying drawings wherein like characters denote like orcorresponding partsthroughout the several views, and in which Figure 1is an elevation with parts in sec- Fig. 2 is a view showin theconnection between the nozzle and hea Fig. 3 is a section on line 3 3 ofFig. 1.

Fig. 4 is a view showing the socket inthehead 11.

` The inner ends of these ports communicate with the passa 9 whichpasses through the projection an the body of the nozzle and ronca.

The head` 1l' is rovided withthe cut away part 12 so t at the nozzlemay. be halved to said head. This partof the head is provided with acone shaped socket 13, i.

which passes entirely through the head and 1s adaptedbto receive theprojection 5. When. the parts Vare positioned the screw threaded end 6w1ll project from the small end of the socket and is adapted to beengaged by the spring washer .14 andthe nut/15.Y Inthis mannerv thenozzle is dly connected with the head. The cone shaped scket has 'anannular groove 16 in its wall, which,

when the parts are assembled, will registerl with the groove 7 in theprojection. A port 17 opens out into this groove 16 and this port is incommunication with the screw threaded socket 18 of the'head whichreceives the shank 19. The other\end of this shank is provided with aconeshaped enlar ement 2,0 which engages the cone shaped soc et 21formed in the end of the stem 22.

The enlargement is rotatably. heldin said socket by'means of the cupshaped nut 23 on vthe shank lil-engaging the screw thread-v ed end ofthe stem. A sprin 24 is placed between the nut and a shoul er 25 formedby the enlargement 20. In this way the` shank ma be rotated in the stemVwhile the spring wil keep:` the 'oint gas tight.

The transverse` wall of the cut away part 12 ofthe head is rounded as at2 6 so that the nozzle ma be swung in an arc of about 270 degrees.

he spring washer will permit this movement of the nozzle while holdingthe parts gas tight.

It will thus be seen that the torch may be moved into any position byineens" of the two joints above described. In this way the torch can beused in an over head position without changing the grip or position ofthe handle, thereby relievin all unnecessary strain on the hand andwrist of the operator.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such cha es fall within the scope of the appended aims.

I claim as my invention Y 1. A torch comprising a shank terminating atone end in a head formed with a conical socket in the side thereof andwith an annular groove extending around saidl socket, a passage disposedin said shank and opening upon said groove, a n ozzle terminating in ahead having a comcal stud on the side thereof adapted to be seatedwithin said socket andv formed with an annular groove extending aroundthe stud in register with said socket groove, a passage disposed in saidnozzle and opening upon said stud groove, and means interposed betweensaidsocket head and said stud head for resiliently retaining said studin gas tight engagement in said socket.

2. A torch comprising a stem'ormed with a conical socket in one endthereof, a passage disposed in said stem and o ening'into the bottom ofsaid socket, a shan terminating at one end in a conical stud adapted tobe seated within said stem socket, said shank being alined with androtatable relative to said stem, means interposed between said shank andstem` for resiliently retaining on the other end of said shank, saidhead being formed with a conical socket in the side thereof and with anannular groove extending around said socket, a passage disposed in saidshank and opening upon the end of said conical stud and upon said socketgroove, a nozzle terminatin in a head having a conical stud on the si ethereof adapted to be seated within said shank socket and formed with anannular groove extending l around the studv in register with said socketREDMOND J.
